GEM-MOUNTING.

Specification of Letters Patent.

Patented June 21, 1910.

Application filed April 5, 1909. Serial No. 487,872.

T 0 all whom it may concern:

Be it known that I, JOSEPH J. BUsER, a citizen of the United States,residing at Freedom, in the county of Beaver and State of Pennsylvania,have invented certain new and useful Improvements in Gem-Mountings, ofwhich the following is a specification.

My invention relates to improvements in gem mountings, and the leadingobject of my invention is the provision of a mounting which willrevolutionize the present system.

of furnishing mountings and provide a mounting whlch will permit theinsertion or application of the gem or stone by any person.

The custom or system in vogue is to furnish the mounting with the prongsunprepared, and when the stone or gem is selected, it is necessary forthe jeweler to have the prongs prepared and fitted, and it is thepurpose of my invention to overcome this objection which occasions lossof time and an expense as well, and to provide direct to the jeweler amounting which will receive the gem or stone and which can be by the jeweler or an unskilled person instantly completed and sold.

With this object in View, my invention consists of a mounting havingprongs constructed to receive and be bent down upon the gem to reliablysecure the gem in proper position.

The invention further consists of a gem mounting embodying novelfeatures of construction and arrangement of parts substantially asdisclosed herein.

In order that the details of construction and the advantages of myimprovement may be readily understood and appreciated, I haveillustrated in the accompanying drawings a gem mounting constructed inaccordance with and embodying my invention.

Figure 1, represents a side elevation of a complete finger ring havingmy novel and improved mounting. Fig. 2, represents a side elevation ofone of the prongs embodying my mounting. Fig. 3, represents an outerface view or elevation of one of the prongs. Fig. 4, represents a sideelevation of a stone in position with two of the prongs, one being bentor forced into engagement with the stone and the other being free orready to be forced into engagement.

The letter A designates a finger ring provided with the series of prongsB, and while I have shown the invention in connection with a fingerring, I would have it understood that the mounting may be used inconnection with studs, scarf pins, brooches, and in fact upon any classor character of jewelry where it would perform the desired function.

In carrying my invention into effect, I provide each prong B with theseat or platform C, upon which rests the stone, and with the extensionI), having its outer face provided with the three tapering or beveledfaces E which form the point or prong F, this construction providing afirm seat or support for the under edge of the stone and giving theprong the desired strength but permitting it to be easily bent down uponthe upper edge of the stone to fasten the stone in position. Tofacilitate said bending of the prong I form in the inner face thereofthe groove G which permits the tip of the prong to be more readily bentdown upon the set and to make a tighter engagement therewith, as mostclearly shown in Fig. 4.

It is evident that I provide a mounting which can be supplied directfrom the manufacturer to the jeweler, and which will permit the stone orgem to be mounted by any person as it is slmply necessary to place thestone in position and bend the prongs down to secure the stone. apparentthat my mounting in addition to saving labor and expense can be producedas cheaply, in fact more cheaply than the mountings in use, and isthoroughly efficient and practical in every particular.

I claim:

In a gem mounting, a series of prongs each having a shoulder formed nearthe upper end thereof and adapted to support the set, the portion of theprong above said shoulder being tapered on the outer edges to bring thesame to a neat and ornamental It is also said groove being ofsubstantially semi-cylindrical shape and being of such size that whenthe prong is bent upon the stone forming the set the edges of the groove10 will make tight engagement with each other.

In testimony whereof I affix my signature, in presence of two Witnesses.

JOSEPH J. BUSER.
